[LG Optimus 2x] racoq:
battery jump from 50% to near 0%

Vadonka, thanks for providing your optimized kernel. The Optimus 2x is thankful for your effort.

I'm writing here to talk about one problem.

My girlfriend optimus 2x is experiencing the same problem zait83 referred:

She also had to take of her battery since her handset freezed completely.

Her handset is using the 3.0.y version from 2012-05-05 (ETaNa_OC_OTF-3.0.y) i've installed this past Saturday , so since zait83 reported for the latest beta, this leads me to believe that this doesn't seems to be a problem of an application but something in recent versions of your kernel.

Just for reference, she has installed WIUI 2.4.20 Stable (gingerbread MIUI) and with the stock kernel she didn't had this problem. The only applications i have in memory that could cause this are antutu battery saver, and setcpu 2.2.4. But again this didn't happened with stock WIUI kernel.

Could this be an issue in your kernel?
[LG Optimus 2x] Gaku86:
Vadonka I have a little problem, after I install the last stable version of the kernel everytime km listening to music my phone turns itself off I dunno why is this, can you please help me

vadonka,

Thank you for your great kernel! Now, when all games (PvZ, Peggle, Sonic 4) that worked on stock CM kernel, now are working on ETaNa, it became the best kernel I ever used.
[LG Optimus 2x] vadonka:
this is happening only when playing music?

happened also some weeks ago now that i remember...
[LG Optimus 2x] DeepEmbrace:
Been trying out "1205072125-ETaNa_STOCK_OTF-3.0.y BETA"

and it is really solid. And when i say solid, im like WTF did you do? :D Some sort of magic? Its very snappy now :)

Battery is a soldier. Gives me a good 8 hours of moderate usage. Another 45-60mins with Antutu battery saver.

Response is waaaaaaay more snappy. Lots of applications pop up faster.

I also got that usb slow speed issue. But after i turned off usb debug, then turned it back on it seemed to fix it. Might just be luck, no real evidence this was the issue.

Im gonna keep this kernel a while longer and play around with voltages and that wifi power app you all talked about :)
[LG Optimus 2x] Gaku86:
Yep only when I'm playing music, but it depends sometimes can take up to 20 minutes and then turns off, some others just after 5 minutes but it is really randomly, it I delete cache and dalvik will this work
[LG Optimus 2x] sushantp666:
Thanks Again. Its great to hav latest 3.0 kernal.
[LG Optimus 2x] umirza85:
Using system tuner pro with the Stock_OC kernel. If i want to set my cpu to 1.4ghz on boot do i choose the option to reapply CPU setting 'on boot completion' or 'init.d script'? is this the only way to set the cpu to 1.4ghz all the time?

Also the only governers i see are powersave and performance? will powersave still allow me to use 1.4ghz? if so does it just take longer to get up to the 1.4ghz speed.
[LG Optimus 2x] ron_gangte:
Waiting for it.

Thank You!

Keep Up the good work! :-)
[LG Optimus 2x] owain94:
no it wont ;)

a couple nighlies after cm 7.1 we got the new userspace drivers

and the kernels these days are not compatible with the old ROMs

so i suggest you to update to for example MIUI or the newest awesome KANG from temasek ;)
[LG Optimus 2x] econ:
Is it stable rom for everyday use? Or has it some minor bugs? Just want to make sure :)
[LG Optimus 2x] vadonka:
the initial first version is up and running in my phone without any issue :)

im still testing it while im writing the CWM script.

almost.... :)
[LG Optimus 2x] ron_gangte:
I've been using the KANG ROMs for quite sometime now. Haven't encountered any problem.

It is very stable and smooth! :-)
[LG Optimus 2x] ChRYs73:
Just to be save is your kernel compatible with MIUI ROM 1.12.30?

TY
[LG Optimus 2x] vadonka:
the short answer is yes :)
[LG Optimus 2x] Medizinmann:
Uhh...ohh..Now,I remember - I read this before...:o:eek: - my mistake...:D

So he has to upgrade anyway...;):D

---------- Post added at 06:30 PM ---------- Previous post was at 06:24 PM ----------

Yes, these are post nightly 204 builds and are a lot more stable then CM7.1 stable ever was...

CM just stopped building CM7 - because the build bot(server) was broken - but not development so far. As I understand it there will be a new CM7.2 stable, but nobody says when – “Always obey CM-Rule #1 – never ask for a release date” ;):D
[LG Optimus 2x] salisbury_steak:
+1 on his suggestion. Or you can use anyone's kang's for that matter. I believe Koboltzz creates nightly kangs still. And dakdroid has his own cherry pick line.

Bottom line, CM7.1 stable is based on older code. And there has been massive improvements, in terms of speed and stability, that came with the recent CM7.2 nightlies. (The working FM radio is one.)

Btw, I flashed a basic kang from Temasek, and deleted the ironkrnl bootanim in data/local. This is in preparation for vadonka's new kernel and scripts. :D
[LG Optimus 2x] koboltzz:
You are right :)
[LG Optimus 2x] TweetyPeety:
would it be possible to add the vorkkernel flagger script, it has everything to do with the update-binary, I can't get them to work.
[LG Optimus 2x] _Vegas:
BTW，the Compcache settings in your script:"Interval in hour" ,that means it will change the size itself every "x hours" ? or any other?

My Compcache size changed to '3804kb' (use the 'auto' value)

the system how to manage the LMK and the COMPCACHE size?
[LG Optimus 2x] fajarep:
congratulation for your kernel :D i believe i'm already gives idea how to control clock when screen on/off at kernel level, and idea how to control second core behavior. eventhough the idea not pure from me, at least i can show the idea is almost like smartass governor...
[LG Optimus 2x] vadonka:
its nice to see you here :)

by the way im almost complete the cwm installer script.

it is a very clean and simple however doing everything :)

build.prop tweak (added new property what is missing, modifyed what is already in there)

installing roboto font, libsqlite patch, kernel modules

todo: ext4 optimization, remove journaling, etc...

my installer is so simple that anyone can be modifyed the build.prop definitions :)

hang in there guys, perhaps im releasing the kernel today :)
[LG Optimus 2x] new2city:
Hanging on since you started this thread... Thanks for the work...
[LG Optimus 2x] ron_gangte:
Eagerly waiting for the first release.

Hope you are making it as stable as possible. Take your time. :-)
[LG Optimus 2x] salisbury_steak:
+1 for stability. I don't care how fast the phone can go if it suddenly crashes on a brick wall, and gives me a BSOD. Or overheats with me doing nothing.
[LG Optimus 2x] vadonka:
im using my kernel over a day now, im not have any problem. its a good start :)

but i wish you guys give me a feedback soon as i release :)
[LG Optimus 2x] ChRYs73:
Roger that :)

just flashed your kernel over at 204-35 Kang using the old CWM without any issues, giving this kernel a go. appreciate retaining vodoo sound support.

:D
[LG Optimus 2x] hardmankam:
I am using CWM v5.0.2.7

Also, does this Kernel needs EXT3 to install? since I am using EXT4, thanks!
[LG Optimus 2x] jefbeck:
currently at 204-35, flashed your latest pwsvr kang, all is well but camera not working.

flashed your latest normal based kang, everything ok. maybe for now......
[LG Optimus 2x] Trystan34:
I am also using 204-35 and latest power save version (32mb hack) and the camera is working fine both with cm7 camera and camera zoom fx.
[LG Optimus 2x] prabhjitsinghwalia:
great job but one problem

i tried ur Jan 9 version and then Jan 12 version but in both of them when the screen is off/locked and then i press the top button it takes a considerably large time to bring the unlocking screen , didn't have that problem when i had ironkernel.

other than that the Kernel works like a charm, Gud job.

I have the Normal Version- Base Version from Jan 12 and the same with Jan 9 version.Rom is Temasek's Cm7 Kng-30.

Also can anyone tell me what values are ideal for normal operations

1) min Cpu Frequency

2) max Cpu Freq

3) Compcache ram usage
[LG Optimus 2x] Rankec:
i use your jan 12 version with powersafe. it works perfectly and battery time is just awesome. 30h with miui and normal use.

best kernel so far :)
[LG Optimus 2x] fuxmen:
Is there any chance to 64MB version?
[LG Optimus 2x] SP1996AC:
1) 216 Mhz will do fine

2) No need to overclock to the max. 1100 Mhz is enough.

3) I think default (18%) will be good enough as well.

[LG Optimus 2x] CVonV:
First (ever) run on jan 13 power save base kernel. It's not the 2 days that's guaranteed but at least it's better than my 8-10 hours on stock temasek/cm7. cpu settings were left on default.

Should I clear battery stats to recalibrate?

Also, just wondering if anybody experiences this too..
[LG Optimus 2x] vadonka:
as i see in your screenshot your phone is aweken a lot, with this condition this battery life is normal.
[LG Optimus 2x] jacobmllr95:
Has someone else the bug with this Kernel (powersave) that the reboot and the boot into recovery functions are not working?

The phone just powers off.
[LG Optimus 2x] SP1996AC:
I don't think it's a bug, did you install the 32MB Ramhack version? Because if you did, the reboot and reboot into recovery doesn't work. Don't worry that's how it's supposed to be with a 32MB Ramhack. If you don't like it then you could always flash the no Ramhack version.

Hello, have problem with google play. If i start apk have error msg.
[LG Optimus 2x] hadi_rena:
Hmmm I notice something weird....

I test read / write speed with sdhci 16 GB class 10 from USB cable. Copying 300 MB file from Laptop to Phone and vice versa and the result is ~10 MB/s write and ~20 MB/s read IF my windows just started. After done some work I perform another test and suddenly write speed dropped to 2-3 MB/s write. OMG something wrong with my laptop ? But I can live with it...

For people who have slow read / write speed please try the test exactly after system boot :D maybe you get something different result

[LG Optimus 2x] sushantp666:
This kernel is too gud in performing,way better than 2.x, but i hav issue with usb tethering,has any 1 hav same issue .i am using latest cyanogen nightly with clean installtion.no issue with same mod with 2.x etana's kernel.
[LG Optimus 2x] vadonka:
what is the problem with the usb tethering exactly?
[LG Optimus 2x] sushantp666:
After starting tethering ,text fadeout and tether not work,no prob with mass storage.i tried enabling and disabling of usb debug,but its not helping.
[LG Optimus 2x] vadonka:
its working with the earlier 3.0.y releases?
[LG Optimus 2x] sushantp666:
No i didnt tried previous version . I directly install 3.0.31 kernel with cyano nightlly.
[LG Optimus 2x] vadonka:
please try the latest stable version, instead of the beta. let me know the usb tethering is working or not.
[LG Optimus 2x] Sörnäinen:
I have the same problem, but it also happened with other background tasks. I blamed the undervolting, since you said stressing the phone could lead to this kind of issue then?
[LG Optimus 2x] elektrotof:
Tested the last stable kernel. Works great but battery life seems to be much shorter than 2.6.y kernel. Go back to last 2.6.y

Nevertheless 3G drains battery so fast in both cases (using Juice Defender).

Thank you for your great work !
[LG Optimus 2x] vadonka:
usb tethering doens't work with kernels above 2.6.35. its a known bug, sorry. it seems we cant use the native usb tethering function for now.
[LG Optimus 2x] TrymHansen:
Hi everybody, a quick heads up that I've made a Torture Tester to test stability at various frequencies/voltages. Works on CM7 w/Etana (likely MIUI as well, but untested at this point.)

You'll be amazed at how quickly the CPUs get (too) hot at 1408.
[LG Optimus 2x] iulian89:
I have a bug that happens when I'm using the gps.

After 20-30 minutes of use, the temperature stays normal, under 40grades but the phone shuts down. No error, nothing just black screen and dead. If I reboot it it reboots without removing the battery. Is there any fix or something?

Using the last stable version

Vadonka, which kernel has the vibrator_strength tweak? Can not find it in 3.0.31 OC_DS_OTF Nevermind, found it.
[LG Optimus 2x] vadonka:
Today beta
[LG Optimus 2x] TrymHansen:
Myrt OTF updated to include the vibrator strength setting.

(I think the driver may need some work though, it does not really change the strength, but the vibration frequency.)
[LG Optimus 2x] brudy:
"Add Vibrator Control v1 by Benee (adjustable from the ETaNa app or realtime)"

I can not find any new option in the ETaNa app.
[LG Optimus 2x] vadonka:
Vibrator Strength

Default value: 3000

Range: 1500-3700

After the sqlite defrag option
[LG Optimus 2x] vadonka:
Trym: you have a permission to upload apps to the Market?
[LG Optimus 2x] TrymHansen:
Yes, I have a market account (two in fact, one for games.) If it's about putting Myrt OTF in the market, then I'll do that when I'm satisfied everything works. Very little feedback so far.
[LG Optimus 2x] brudy:
Ok, I see. Sorry. :o
[LG Optimus 2x] vadonka:
activated after reboot, for real time change you need to use the new MyrtOTF app.
[LG Optimus 2x] vadonka:

testing new beta..playing music..but after i press next song,,phone freeze and power off..need to switch on phone..btw thanks for you hard week!! really like your kernel!
[LG Optimus 2x] vadonka:
strange, what music player you used? and using the lock screen music control or not?

im using winamp but i dont have this issue.

edit: tryed with poweramp, default cm7 music app. non of them have this issue.

ohh and please do this:

- connect the phone to the PC

- adb logcat > c:\logcat.txt

- dont interrupt!

play the music then try to choose the next song and if the phone is freeze/powered off, stop the adb command with ctrl+c

then give me the logcat.txt file

that would help a lot

Guys!

Next time if you report an issue please include the following information:

-kernel/rom version

-CPU UV active or not

-what was the foreground app when the issue occured?

-can you reproduce the issue?

-if yes describe what you do

thx!
[LG Optimus 2x] plakers:
If you want "all" functions :

- etana's tweakaio.conf config file

- HP OTF and Myrt OTF (some are in the first one, other in the second one...)

Could be so great to get all options in one app... (tweakaio + all otf ones) :D
[LG Optimus 2x] vadonka:
yeah i want it too, let me know if you find someone who can write such an app ;)

my java knowledge is almost zero :D
[LG Optimus 2x] tonyp:
People tend to complain more than give positive feedback, I think you're good to go ;)
[LG Optimus 2x] ron_gangte:
+1

I'd want an all-in-one app to control all values, preferably like the Gueste Kernel App.

@TrymHansen : A lot of us would appreciate an exclusive app for ETaNa Kernel. Please make an app for ETaNa!! :-(
[LG Optimus 2x] vadonka:
i separated the otf code and move everything to the drivers/misc/otf

so it is a lot more easier to integrate in any other kernel
[LG Optimus 2x] TrymHansen:
I hear you, I really do.

I made GuesteOC because I liked the premise of the kernel, and because I wanted to support Stefan. He put some things in there which still aren't available in other kernels. So I hoped a nice app would attract some more users for him.

Etana already *has* an app. It may not be realtime or quite as polished, but it does what it's supposed to do. Even in GuesteOC I did not include all of the available OTF-settings, because I strongly believe you should know what you're doing before messing with them, and if you do there's no need for an 'easy' app.

(By the same token, that's why I haven't made apps to adjust the thousands of parameters you can adjust in any kernel. If you really need it you already know what to do.)

Apps take time. I've spent months on these apps combined, and that has earned me perhaps 2 or 3 sales of my paid app. Not enough to even pay for the market account fee. As I've stated before it's rewarding in its own way to make free apps, and I appreciate the largely positive feedback, but in real life that's not enough.

Don't get me wrong, I've never demanded anything in return for these apps, they are truly free apps, no strings attached, I'm just trying to say that I cannot go on spending all my time making them.

*If* I were to make an app for Etana, it would be a new kind of app, one with no settings hardcoded in the app itself, but dynamically creating the interface depending on what it can find in the config-files. Before Spica finalized the first OTF-version I asked him to make it easier to find the default value of a setting, which didn't happen. Without defaults and limits easily available somewhere I don't think that kind of app is going to happen. But wouldn't that be nice? Any kernel-compiler could add any setting at any time, and the app would automatically create an interface for it. All we need is a well-defined standard for any OTF-type setting, including limits and defaults and where to write the live-value.

I'm not saying I'll stop writing free apps, au contraire I probably will everytime I'm experimenting with something, but I just cannot promise it, and it will certainly not be apps duplicating the functionality of other apps like the Etana Tweaker.

I have no idea how this suddenly turned into a wall-of-text, sorry about that. Do try the Myrt Torture Tester, I think everybody can learn something about their device if they experiment a bit with that. (Don't touch the temperature-cutoff values and you should be fine.) Sorry for the sleepy ramblings.
[LG Optimus 2x] vadonka:
Thank you for your all effort

you writed great apps, this helps a lot :)

about the otf

Spica use the proc filesystem for the otf one file for every value, he dont have much time because his day job so i continue advance the otf.

the first step is using a separated folder for everything in the source. currently every otf value is located in one file.

the next step is modifyed this files that used the sysfs instead of the procfs

and i will integrate some other value too like min max value and default. this values will be read only its just for the record.

i also have some idea about expand the otf with some other things too.

im still not so experienced like Spika or Benee but i have an ability for learn insanly fast :p
[LG Optimus 2x] TrymHansen:
That sounds good. From the perspective of an app maker it would be great if there was a central location to go to query the kernel about what settings it provides. They'd have to have a "category", so that related settings can be grouped together, type of value (boolean, int, float or array of choices), min/max/step values, and a short unique descriptor which can be used to look up user-supplied localized names, descriptions & help. And that's all really, if the standard is well thought-out there should be some room for expanding it without breaking anything. (This is basically what I hoped would be in the first OTF.) (You can even imagine a startup program which creates an sqlite-database collected from this info, so the app wouldn't have to query the kernel at all, but that's probably overkill.)

The day you make a kernel for CM9 I'll switch ;-)
[LG Optimus 2x] Shadowchaz:

[LG Optimus 2x] pidocchio:
anyone having problems with Google Currents app?

on both 2.6.y and 3.0.y kernels this app is laggy as hell, cpu goes to 100% use with some sort of overload spikes very often (several times in a minute maybe one spike every 5 seconds) making this app unusable and very annoying.

is this a kernel related problem?

currently i'm using 3.0.y 05/06 OC Stock version @1.2Ghz with ramhack set to 48MB and no other changes from stock values in etana's otf app.
[LG Optimus 2x] slebit:
Maybe a stupid question but I will ask it anyway. If you use ramhack is the battery draining faster? Because after a few week I have noticed a differens in battery drain when using ramhack.
[LG Optimus 2x] yarisd4dturbo:
+1 for me, all work smooth and the kernel is more stable, i'm using last beta on miui ;)
[LG Optimus 2x] :
Vadonka,

In your latest 2.6 kernel, setting nitros on in the Etana conf app doesn't reflect in /proc/spica/nitros, it still says 0 there. The rest works. Haven't tested on 3.0 yet...
